Definitions
- a cap may be used on a vessel containing a liquid to minimize the evaporation of the liquid and to prevent accidental spillage that may occur when the vessel is moved.
- components such as electric components or connectors that are immersed in or expand to liquids must be protected with a cover so as to avoid deleterious effects that could be caused by exposure of the component to the liquid.
- Nuclear reactors typically include various forms of instrumentation.
- in-core instruments can be positioned near the fuel bundle or core to measure various parameters associated with the core's performance.
- These instruments can include, for example, core exit thermocouples and rhodium detectors.
- the core exit thermocouples measure the temperature of fluid as it exits the core, and the rhodium detectors measure neutron density, which is related to the power level in the core.
- Maintenance activities in the reactors sometimes involve moving the core or removing the reactor vessel internals. During such activities the chamber or vessel in which the in-core instrument's electrical connectors are located is flooded with water to minimize the potential for radiation doses to workers performing the maintenance activity. Moreover, the connectors oftentimes have to be de-mated or disconnected as part of the maintenance activities, leaving one end of the connector open and exposed to the surrounding environment.
- the exposed ends of the de-mated connectors Prior to the time the vessel is flooded, the exposed ends of the de-mated connectors must be covered or sealed in order to isolate and protect them from the water. These ends are typically protected with a metal cap.
- these metal caps have included an o-ring to provide a seal between the connector and the cap in order to protect the exposed end of the connector from the water in which it is immersed.
- the metal caps may leak, particularly if they are not properly installed, or because the o-ring has become loose or disengaged.
- maintenance activities oftentimes involve working with long handled tools which are dipped into the water to perform certain tasks. These tools occasionally impact the metal caps, which can dislodge them from the connector if they are not properly installed. Consequently, the fact that the metal caps are not properly installed oftentimes lead to undesirable results.
- a cap that leaks or is dislodged will allow water to flood the exposed end of the connector, which may then need to be reworked to replaced to recover its critical electrical capabilities.
- the metal caps usually include a lanyard attached to the connector or a nearby surface to capture the cap in the event it is dislodged from the connector.
- the lanyards are oftentimes cut or otherwise removed because they can interfere with, and extend the time needed, for maintenance activities. Time can be of the essence in the nuclear reactor environment, because of both the possibility of radiation exposure to workers, and the loss of revenues while the power plant is off-line. Consequently, an incentive exists to cut any lanyard that is interfering with maintenance activities.
- Apparatus can be installed onto an exposed end of an instrumentation electrical connector, to protect the exposed end of the connector from a surrounding body of liquid.
- the apparatus can include a shell having a closed first end formed from a liquid resistant shell material, a second end, and a skirt portion extending therebetween. The second end can have an opening therein for insertion onto the exposed end of the connector.
- a compression operable seal can be positioned in a seal groove adjacent an inside surface of the skirt portion and adjacent the first end.
- the seal groove can include a trough adjacent the inside surface.
- a connection means on the internal surface can be adapted to matingly engage an external surface on the connector, and to move the shell material towards the exposed end of the connector when the apparatus is moved to an installed condition. When the apparatus is in the installed condition, the shell material can compress the seal against the exposed end to form a substantially leak proof barrier between the exposed end of the connector and the body of liquid.
- Either the shell, seal, or both can have a specific gravity less than the specific gravity of the liquid, but in either case the shell and seal have a combined specific gravity that is less than the specific gravity of the liquid to give the apparatus flotation capability.
- At least a portion of an outside surface on the shell can be of a color that contrasts with the color of the installation environment.
- the seal can include a wave washer
- the shell can include a visual installation position indicator and an outside surface with a gripping means.
- a method for protecting an exposed end of an instrumentation connector in a nuclear reactor from a surrounding body of liquid.
- the method includes extending an internal surface on a shell over an external surface on the connector, removably connecting the internal surface to the external surface, providing at least a portion of the shell with a liquid resistant shell material, positioning the shell material over the exposed end of the connector, positioning a compression operable seal between the shell material and the exposed end of the connector, and moving the shell to an installed condition wherein the seal is compressed between the shell material and the connector to form a substantially leak-proof seal.
- FIG. 1 is a fragmented frontal elevation view of an embodiment having features found on the present invention, in an uninstalled condition;
- FIG. 2 is a fragmented frontal elevation view of apparatus with an alternative embodiment seal
- FIG. 3 is a fragmented frontal elevation view, of the embodiment shown in FIG. 1, in an uninstalled condition.
- FIG. 1 shows apparatus ( 20 ), which can be installed onto the exposed or de-mated end ( 22 ) of an instrumentation connector ( 24 ) to protect the connector from a surrounding body of liquid.
- the connector geometry can vary, but in general such connectors will have an external surface ( 26 ) with a diameter (D 1 ).
- the connector may include threads ( 28 ) and a length (L 1 ) from the exposed end ( 22 ) to a bottom thread ( 30 ).
- the apparatus ( 20 ) can include a shell ( 32 ) with a closed first end ( 34 ) formed from a liquid resistant shell material.
- the liquid resistant shell material is impermeable to water, or other liquids in which the apparatus might be immersed, and can be a material such as polypropylene or the like.
- the shell material can have a specific gravity less than the specific gravity of the liquid. For example, if the shell is to be immersed in water, the shell material can have a specific gravity of less than one.
- the purpose of having a specific gravity less than one in a water filled environment is to provide the apparatus with flotation capability.
- the first end ( 34 ) is referred to as “closed” because it does not contain any holes, perforations, apertures or the like which could establish a pathway between the exposed end of the connector and a surrounding body of liquid. Consequently the closed first end, formed from the liquid resistant shell material, can function as a barrier to water or other liquids. If desired, the entire shell can be a unitary construction made from one liquid resistant shell material.
- the shell includes a second end ( 36 ) and a skirt portion ( 38 ) that can extend for a length (L 2 ) from the first end to the second end.
- An opening ( 40 ) may be positioned in the second end having a diameter (D 2 ).
- the length (L 2 ) and diameter (D 2 ) can be predetermined depending upon the configuration of the connector ( 24 ).
- the length (L 2 ) can be selected to place the second end surface ( 42 ) even with the bottom thread ( 30 ) or reference line ( 31 ) on the connector when the apparatus is properly installed.
- the end surface ( 42 ) of the second end can function as a visual installation position indicator to demonstrate the proper installation of the apparatus
- the skirt portion ( 38 ) includes an internal surface ( 46 ) with a connection means ( 48 ) which can be matingly engaged with the external surface ( 26 ) on the connector.
- the connection means will correspond to the connector configuration and can be, for example, a threaded connection, a quarter turn connection, or other types of connections known to skilled artisans and which can be used to removably attach the shell to the connector. Additionally, the connection means is preferably one which will facilitate the translation, along centerline (CL 1 ), of the first end ( 34 ) towards the exposed end ( 22 ) when the shell is rotated into an installed condition.
- a compression responsive seal ( 50 ) can reside adjacent the inside surface ( 46 ) of the skirt portion ( 38 ) and adjacent the first end ( 34 ).
- the seal can be a gasket placed into a circular seal groove ( 52 ) having a lip ( 54 ) integrally formed with the first end.
- the seal groove can also include a trough ( 55 ) into which the seal extends.
- the trough includes a ledge ( 57 ) which aids in retaining the seal 30 within the seal groove.
- the seal is preferably made from neoprene, but it can also be made from other materials known to skilled artisans that are compressible and impermeable to water or other liquids into which the apparatus may be immersed. If desired the seal can also be bonded to the shell using means known to skilled artisans.
- the gasket has a diameter (D 3 ) and width (L 3 ) that are selected, in accordance with connector diameter (D 1 ), to place a portion of the width of the gasket into compressive contact with the exposed end ( 22 ) of the connector when the apparatus is in an installed condition.
- the gasket material can be made with a material having a specific gravity less than the specific gravity of the liquid. In any event, the composite (i.e., combined) specific gravity of the shell ( 32 ) and seal ( 50 ) will be less than the specific gravity of the liquid into which the apparatus is immersed to ensure that the apparatus will float.
- FIG. 2 depicts an alternative embodiment in which the seal ( 50 ) can comprise a gasket ( 56 ) and a wave washer ( 58 ).
- the wave washer ( 58 ) can be positioned between the gasket ( 56 ) and the first end ( 34 ). If a seal with a wave gasket is used, a flat washer ( 59 ) can be positioned between the gasket and wave washer in order to minimize contact irregularities then might exist if the wave washer were to bear directly against the gasket.
- All or a portion of the shell's outside surface ( 60 ) can be provided with a contrasting color.
- the shell can be made from materials having the desired color, or the desired color can be applied to a prefabricated shell.
- the term “contrasting color” can mean any color which contrasts with the color or colors of the installation environment.
- the outside surface ( 60 ) of the shell ( 32 ) can be provided with a gripping means to facilitate the gripping and turning operations that an operator may employ when installing and removing the apparatus from a connector.
- the gripping means can comprise a knurled surface (not shown) or a series of splines ( 62 ) integrally formed in the outside surface.
- the desired configuration of the apparatus is determined based upon the design of the de-mated or exposed connector and the installation environment.
- the outside surface ( 60 ) of the shell ( 32 ) is provided with a color that will contrast with, and be easily visible in, the nuclear reactor installation environment. While the exact color can depend upon the color or colors of the installation environment, it is expected that colors such as orange, yellow, red and or white will likely be well suited for use in most nuclear reactors. It is also expected that the apparatus will be immersed in water during maintenance activities performed in nuclear reactors, so the apparatus will typically be fabricated with a composite specific gravity that is less than one. The specific gravity can be adjusted to provide flotation capability in other liquids if necessary.
- the opening ( 40 ) on the second end ( 36 ) is inserted over the connector's exposed end ( 22 ), and the shell's internal surface ( 46 ) is extended over the connector's external surface ( 26 ) until the threads ( 28 ) and connection means ( 48 ) are in contact with each other.
- the compression operable seal ( 50 ) is positioned between the first end ( 34 ) and exposed end ( 22 ).
- the entire shell may be made from the liquid resistant shell material, but in any event, the portion of the first end ( 34 ) within the outer circumference of the seal is made with such shell material.
- the apparatus can be rotated to engage the threads and removably attach the internal surface to the external surface.
- the first end ( 34 ) of the shell ( 32 ) is forced towards the exposed end ( 22 ) of the connector ( 24 ).
- the end surface ( 42 ) on the shell is visually examined during the installation process to determine its position relative to the bottom thread ( 30 ).
- another type of position indicator may be used in lieu of bottom thread ( 30 ), such as a reference line or mark ( 31 ).
- this indicates to the operator that the apparatus is in the installed condition. In the installed condition the threads, or other types of connection means which may be used, have the desired degree of engagement to firmly retain the apparatus on the connector.
- the internal surface ( 46 ) can help guide the connector into the proper engagement with the seal ( 50 ).
- the connector wall thickness ( 66 ) will bear against a portion of the seal that is inward from the outer edges of the seal. As the seal is compressed, it responds by bearing against surfaces in the seal groove and against the connector to form a substantially leak proof barrier between the exposed end of the connector and the body of liquid in which the connector and apparatus are immersed.
- a wave washer may be desired when connectors with quarter-turn fastening means are used. Quarter turn fasteners may not develop the level of force necessary to maintain a desired degree of compressive force between the seal and the connector. In such a case the wave washer will provide a supplemental force that will assist in maintaining the sealing arrangement.
- the pressure vessel or other chamber in which the connector resides can be filled with water.
- the apparatus becomes dislodged, its buoyancy will carry it to the surface of the water where it can be easily retrieved.
- the shell's contrasting color will further facilitate retrieval of the apparatus, whether or not it is found loose in a dry or a wet vessel or chamber.
- the apparatus can pose less of a foreign-object-damage risk, since it is constructed of materials such as polypropylene and neoprene, than the metal caps which are traditionally used.
